The objective of medical research is the quest for scientific truth, as well as the communication of new knowledge to the medical society through publication of novel results. Journals publishing these results rely on the trust that all persons involved (authors, peer reviewers, editors, and publishers) remain honest, following the rules and ethics of scientific integrity. Unfortunately, this is not always the case and a wide spectrum of pitfalls and misconducts may occur, ranging from less serious violations of ethical rules to most serious ones. In ascending order of severity, these include borderline questionable practices (HARKing [Hypothesizing After the Results are Known] and hyping), redundant publications, authorship misconducts, plagiarism, and all types of fraud (data falsification or fabrication). Awareness of all these fraudulent practices is essential to mitigate misconduct in academic writing.
